Class Work Let’s start with some review!! 1.Solve for x. x 7 42 

Trig – Section 6 Law of Sines Objectives: To understand how to use the Law of Sines to solve any triangle.

Law of Sines The Law of Sines says that in any triangle the lengths of the sides are proportional to the sines of the corresponding angles. A B C a b c

Ex 1. Solve the triangle when given ASA. 30  A B C a b 100 40 

Ex 2. Solve the triangle (AAS)

Class Work 5. Solve for x. Round answers to nearest tenth.

6. Solve for x. Round answers to nearest tenth.

You can also use the Law of Sines for two sides and an angle (SSA). Ex 3. Solve  ABC if m  A = 80 , a = 100 and b = 10

Ex 4. Solve  ABC if m  A = 41 , a = 40 and b = 89.

Class Work 7. Solve  ABC if m  A = 80 , a = 6.5 and b = 3.4 8. Solve  ABC if m  A = 80 , a = 10 and b = 100
